An apparatus has been known which is used for automatically painting wax over the body surface of a vehicle after washing and drying operations. But any automatic polishing apparatus for a vehicle has not been provided. And polishing operation of a vehicle used to be performed manually.

Therefore,'the main object of the present invention is to provide a polishing device for a vehicle which is simple in structure and operates efficiently in polishing the body surface of a vehicle, by only sliding a circumferential outer portion of a buff body spirally surrounding a rotating shaft, over the body surface of the vehicle.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings annexed hereto,

FIG. 1 is a partial sectional view of the device according to the present invention,

FIG. 2 shows the device in a condition of polishing the body surface of a vehicle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS There is seen a polishing body 3 which spirally surrounds a rotating shaft 1 supported between a pair of swing arms 2, 2.

The polishing body comprises a pair of apiral plates 4 both radially expanding from the circumferential surface of the shaft 1 in side-to-side abutting relationship, and a spiral buff body 5 which is clamped by the spiral plates along its root side edge. The polishing body 3 is to polish the body surface of a vehicle V.

In operation, the circumferential outer portion of the spiral buff body 5 will brushingly polish the body surface of the vehicle V when the rotating shaft 1 is rotated by a drive means (not shown), after the polishing body 3 is brought into contact with the body surface of the vehicle V.

Thus, according to the present invention, the body surface of the vehicle is effectively polished by the polishing body which rotated with the rotating shaft. And particularly, the body surface of the vehicle is speedily and effectively polished evenly if the buff body 5 is a thin one because of its spiral shape. Moreover, the device can be formed to be a light and economical one.

What is claimed is:

l. A polishing device for a vehicle comprising a rotating shaft, a spiral buff body surroundingly attached to said shaft by means of spiral attaching means radially expanding from the circumferential surface of said shaft, and a pair of swing arms rotatably supporting said shaft between said swing arms, said spiral attaching means comprising a pair of spiral plates both radially expanding from the circumferential surface of said shaft in side-to-side abutting relationship, said plates forming a spiral concave opening outwards along their ral buff body. 

1. A polishing device for a vehicle comprising a rotating shaft, a spiral buff body surroundingly attached to said shaft by means of spiral attaching means radially expanding from the circumferential surface of said shaft, and a pair of swing arms rotatably supporting said shaft between said swing arms, said spiral attaching means comprising a pair of spiral plates both radially expanding from the circumferential surface of said shaft in side-to-side abutting relationship, said plates forming a spiral concave opening outwards along their outer edges for clamping the root side edge of said spiral buff body.
